Alias I use for switching branches

fzf_branch_selection.zsh

# fuzzy finder branch selection
# if run by itself, switches to the selected branch
# if run in a subshell, echos the selected branch
function fgb() {
  if [[ "$ZSH_SUBSHELL" == "0" ]]; then
    git checkout $(fgb)
  else
    gbranches |
      fzf --height 40% --ansi |
      awk '{print $1}' |
      sed 's#^remotes/[^/]*/##'
  fi
}

function gbranches() {
  local ansi_reset="\\e[0m"
  local ansi_dim="\\e[2m"
  local ansi_green="\\e[32m"
  local ansi_yellow="\\e[33m"
  git branch |
    sed 's/^..//' |
    ruby -e "puts STDIN.read.split(/\n/).map { |b| b = b.split.first; [b, %x(git log --format='%ai ${ansi_dim}%hi${ansi_reset} ${ansi_yellow}%s${ansi_reset}' #{b} | head -1)] }.sort_by(&:last).reverse.map { |b, c| %(${ansi_green} #{b.ljust(50)} ${ansi_reset} #{c}) }"
}
